When humanity, after failing its driver's test for Planet Earth, decides the only solution is to hotwire the climate system with planetary-scale tech. It’s the desperate Hail Mary of climate change, involving massive interventions like spraying reflective aerosols into the stratosphere to bounce away sunlight (Solar Radiation Management) or seeding the oceans with iron to suck CO2 out of the air. Critics call it a dangerous, global-scale experiment with potentially catastrophic side-effects, like messing up monsoon rains. Proponents argue we're already running an unintended experiment by burning fossil fuels, so we might need a giant thermostat.
